L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans
Denis Defrère, Azzurra Bigioli, Colin Dandumont +34
Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…
Optimal Real-time Coordination of Distributed Energy Resources in Low-voltage Grids
Sen Zhan, Johan Morren, Wouter van den Akker +2
This study proposes a real-time distributed energy resource (DER) coordination model that can exploit flexibility from the DERs to solve voltage and overloading issues using both a…
MARVEL, a four-telescope array for high-precision radial-velocity monitoring
Gert Raskin, Christian Schwab, Bart Vandenbussche +23
Since the first discovery of a planet outside of our Solar System in 1995, exoplanet research has shifted from detecting to characterizing worlds around other stars. The TESS (NASA…
PLC-controlled cryostats for the BlackGEM and MeerLICHT detectors
Gert Raskin, Johan Morren, Wim Pessemier +5
BlackGEM (BG) is an array of telescopes, currently under development at the Radboud University Nijmegen and at NOVA. It targets the detection of the optical counterparts of gravita…
Compact Stirling cooling of astronomical detectors
Gert Raskin, Johan Morren, Wim Pessemier +2
MAIA, a three-channel imager targeting fast cadence photometry, was recently installed on the Mercator telescope (La Palma, Spain). This instrument observes a 9.4 x 14.1 arcmin fie…
MAIA, a three-channel imager for asteroseismology: instrument design
Gert Raskin, Steven Bloemen, Johan Morren +8
MAIA, an acronym for Mercator Advanced Imager for Asteroseismology, is a three-channel instrument that targets fast-cadence three-colour photometry, installed at the 1.2-m Mercator…
HERMES: a high-resolution fibre-fed spectrograph for the Mercator telescope
Gert Raskin, Hans Van Winckel, Herman Hensberge +18
The HERMES high-resolution spectrograph project aims at exploiting the specific potential of small but flexible telescopes in observational astrophysics. The optimised optical desi…
